Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a charged particle beam exposure method and a charged particle beam exposure system in which nonuniformity of CD (line width of pattern) due to fogging is improved.  <P>SOLUTION: In the exposure of subfield rows (electrical stripes) on a reticle 10, a variation in line width due to the effect of a non-patterned charged particle beam dose (fogging) on a wafer 23 is made uniform by varying the shot time through control of a blanking opening 7 while sustaining a constant shot cycle. Fogging is significant in the central part of the wafer and insignificant on the circumference. In the subfield on the circumference of the wafer, a normal exposure time (shot time) is set and the shot time of a subfield in the central part of the wafer is varied to become shorter than the shot time of a subfield on the circumference.  <P>COPYRIGHT: (C)2004,JPO
